how to get 'sub-level' components from a xml schema

["Kahovec, Jakub" <j....@imperial.ac.uk>]

Hi,
when I use

itemPSVI = (ItemPSVI)node;

XSModel model = ((ElementPSVI) itemPSVI).getSchemaInformation();

XSNamedMap map = model.getComponents(XSConstants.ELEMENT_DECLARATION);

I got only the top level components, but I would like to get sub-level componens which are related to a node.

For instance in following example how can I get sub-components (child nodes) of the Info element ?

 <xs:element name="MqatDocument">
  <xs:complexType>
   <xs:sequence>
     <xs:element ref="Info" minOccurs='1' maxOccurs='1'/>
     <xs:element ref="Question" minOccurs='1' maxOccurs='unbounded'/>
   </xs:sequence>
  </xs:complexType>
 </xs:element>

 <xs:element name="Info">
  <xs:complexType>
   <xs:sequence>
      <xs:element name="Title" type='xs:string'/>
      <xs:element name="Author" type='xs:string'/>
      <xs:element name="Version" type='xs:string'/>
      <xs:element name="Date" type='xs:string'/>
   </xs:sequence>
  </xs:complexType>
  </xs:element>
 
Thanks for any ideas.

Get the 'XSElementDeclaration' directly from the 'ElementPSVI' and 
analyze its type definition. If the type definition is a complex 
type specifying mixed or element-only content you could analyze the 
content model group particle (i.e. the children which are possibly 
local declarations) further, and so on recursively for any child 
element declarations, if you need.
